一种籽瓜收获机用瓜蔓分离装置A melon vine separation device for a seed melon harvester

技术领域technical field

本发明涉及农业机械技术领域，特别是涉及一种籽瓜收获机用瓜蔓分离装置。The invention relates to the technical field of agricultural machinery, in particular to a melon vine separating device for a seed melon harvester.

背景技术Background technique

籽瓜是我国西北地区的一种重要经济作物，这类农作物主要是用于获取瓜籽，瓜籽具有食用经等济价值，其收获机统称为籽瓜收获机。由于籽瓜具有藤蔓，其收获作业较为复杂，较难采用机械进行收获。现有技术中，专利CN209845732U公开了一种籽瓜收获机用捡拾装置及籽瓜收获机，该装置中，利用喂入搅龙将籽瓜距离到中间，再利用带有扎钉的捡拾滚筒对籽瓜进行捡拾，并在捡拾过程中利用上切割器将藤蔓切断，这种结构中，藤蔓的切割时机较晚，在搅龙将瓜向中部聚拢以及拾取籽瓜的过程中，藤蔓容易错综纠缠，导致卡塞，因此有必要设计一种能够对籽瓜与藤蔓进行前置分离处理以方便后续捡拾的籽瓜收获机用瓜蔓分离装置。Seed melon is an important economic crop in Northwest my country. This kind of crop is mainly used to obtain melon seeds. Because the seed melon has vines, its harvesting operation is comparatively complicated, and it is difficult to adopt machinery to harvest. In the prior art, the patent CN209845732U discloses a pick-up device for a seed melon harvester and a seed melon harvester. In this device, the seed melon is separated to the middle by a feeding auger, and the pick-up roller with nails is used to pick up the seed melon , and use the upper cutter to cut off the vines during the picking process. In this structure, the cutting time of the vines is relatively late. When the auger gathers the melons to the middle and picks up the seed melons, the vines are easy to become entangled, resulting in jamming. Therefore, it is necessary to design a kind of melon and vine separation device for seed melon harvester that can carry out pre-separation treatment on seed melon and vines to facilitate subsequent picking.

发明内容Contents of the invention

发明目的：为了克服现有技术中存在的不足，本发明提供一种能够有效分离籽瓜与藤蔓、且利于籽瓜捡拾的籽瓜收获机用瓜蔓分离装置。Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a melon and vine separation device for a seed melon harvester that can effectively separate the seed melon from the vines and facilitate the picking of the seed melon.

技术方案：为实现上述目的，本发明的籽瓜收获机用瓜蔓分离装置，其包括能够主动转动的辊体，所述辊体的中心轴相对于左右方向倾斜安装，此处以机具的前进方向作为前方；还包括在所述辊体的轴向上排布的多组藤蔓分离机构；所述藤蔓分离机构包括循环单元以及沿着所述循环单元等距安装的多个条状体；所述辊体的下侧设置有对应于每组所述藤蔓分离机构设置的割刀；所述循环单元下端的两侧均设置有所述割刀，且所述条状体沿着所述循环单元运转从两侧的所述割刀之间穿过。Technical solution: In order to achieve the above object, the melon and vine separation device for the seed melon harvester of the present invention includes a roller body that can actively rotate, and the central axis of the roller body is installed obliquely relative to the left and right directions, and the forward direction of the machine tool is used as the The front; also includes multiple groups of vine separation mechanisms arranged in the axial direction of the roller body; the vine separation mechanism includes a circulation unit and a plurality of strips installed equidistantly along the circulation unit; the roller The lower side of the body is provided with a cutting knife corresponding to each group of the vine separation mechanism; both sides of the lower end of the circulation unit are provided with the cutting knife, and the strip runs along the circulation unit from Pass between the cutters on both sides.

收获时，辊体转动，由于籽瓜较大而藤蔓较细，因此籽瓜被辊体推着前进，而藤蔓会被条状体勾住并随着条状体向下运动并通过两侧的割刀而被割断，如此，藤蔓会被切断成较短的段体；同时，由于辊体的中心轴相对于左右方向倾斜安装，因此被切断所连接的藤蔓的籽瓜会相对于辊体向斜后方运动，并从辊体的靠后一端脱离辊体，如此籽瓜被集中在一个较窄的条带上，方便捡拾。When harvesting, the roller body rotates. Since the seed melon is larger and the vines are thinner, the seed melon is pushed forward by the roller body, and the vine will be hooked by the strip and move down with the strip and pass through the cutting knives on both sides. In this way, the vines will be cut into shorter segments; at the same time, since the central axis of the roller body is installed obliquely relative to the left and right directions, the seeds of the vines connected by the cut off will move obliquely rearward relative to the roller body , and detach from the roller body from the rear end of the roller body, so that the seeds are concentrated on a narrow strip for easy picking.

进一步地，所述循环单元为条状的循环单元，其具有位于前侧的竖向段；所述辊体的上端安装有主动轮，所述循环单元的上端绕过所述主动轮；所述辊体具有环槽，所述藤蔓分离机构还包括伸入所述环槽内的从动轮，所述循环单元的下端绕过所述从动轮。Further, the circulation unit is a strip-shaped circulation unit, which has a vertical section on the front side; a driving wheel is installed on the upper end of the roller body, and the upper end of the circulation unit bypasses the driving wheel; The roller body has an annular groove, and the vine separation mechanism further includes a driven wheel protruding into the annular groove, and the lower end of the circulation unit goes around the driven wheel.

Lateral movement. The above-mentioned vertical section has a part extending upwards from the ring groove, which can block the vines and move the vines downward through the strips thereon, so that the vines will not cross the roller body from the upper side of the roller body. Along with the operation of the circulation unit, the strip-shaped body gradually stretches out from the lower side of the front side of the roller body, hooks the vines and transports the vines from the lower side of the roller body to the rear. This way, the strips do not interfere with the seed melon.

进一步地，所述辊体包括多个辊段，所述环槽形成在相邻的两个所述辊段之间，且相邻的两个辊段之间通过连接部连接；所述从动轮位于所述连接部的下侧。Further, the roller body includes a plurality of roller segments, the annular groove is formed between two adjacent roller segments, and the two adjacent roller segments are connected by a connecting part; the driven wheel Located on the lower side of the connecting part.

进一步地，所述藤蔓分离机构还包括机构架体，所述机构架体具有伸入每个所述环槽内的伸出架，所述从动轮转动安装在所述伸出架上。Further, the vine separation mechanism further includes a mechanism frame body, the mechanism frame body has an extension frame protruding into each of the ring grooves, and the driven wheel is rotatably mounted on the extension frame.

进一步地，所述割刀也安装在所述伸出架上。Further, the cutting knife is also installed on the extension frame.

进一步地，所有所述主动轮均安装在同一个驱动轴上，所述驱动轴与所述辊体之间通过链条建立传动关系。Further, all the driving wheels are mounted on the same drive shaft, and a transmission relationship is established between the drive shaft and the roller body through a chain.

有益效果：本发明的籽瓜收获机用瓜蔓分离装置，通过设置斜置的辊体以及包含条状体的循环单元，利用籽瓜与藤蔓两者特征上的区别，可实现籽瓜与藤蔓的有效分离并及时将藤蔓切断，籽瓜能够随着辊体的推进运动至辊体的侧后方聚集成条带状的籽瓜带，方便后续捡拾。相比于现有技术，其先将籽瓜与藤蔓进行分类，同时使籽瓜向一侧聚拢方便捡拾，可有效避免收获过程中藤蔓错综缠绕的问题。Beneficial effects: the melon and vine separation device for the seed melon harvester of the present invention can realize the effective separation of the seed melon and the vine by using the difference in characteristics between the seed melon and the vine by setting the oblique roller body and the circulation unit containing the strip And the vines are cut off in time, and the seed melons can be gathered to the side and rear of the roller body along with the advancing movement of the roller body to form a strip-shaped seed melon belt, which is convenient for subsequent picking.
